From Day of the River:Murase Kokona is a normal high school girl, but the one thing she hates the most in the entire world is men. On the day of the high school entrance ceremony, Kokona rescued a bishoujo from a group of idiotic, stupid foul men. Unexpectedly, this person turned out to be Misaki Hiromu (male) and goes to the same school!!

However, Kokona, who gets goosebumps everytime she's touched by a man, doesn't seem to have any physiological reactions around Misaki….?
